  • The theory of weak interaction explains how particles interact via the weak force, which is responsible for certain types of radioactive decay.

Examples

  • And since we had just been enriched with a renormalizable theory of the electromagnetic interactions, the foremost goal was to renormalize the theory of weak interactions.

    Academic text (1999)
  • According to the theory of weak interaction, neutrinos can change their type, a process known as flavor oscillation.

  • Research in particle physics often tests the predictions made by the theory of weak interaction regarding subatomic processes.

Morphology

theory + of + weak + interaction

The phrase is fully compositional: a B1 learner who knows 'theory' (an explanatory framework), 'weak' (not strong), and 'interaction' (a reciprocal action) can infer this is a theory about a weak type of interaction. While the specific scientific details (e.g. fundamental force, beta decay) are specialized knowledge, the noun-phrase structure 'theory of X' and the modifier 'weak interaction' are predictable and cross-linguistically common, making the MWE transparent.

Etymology

The noun theory of weak interaction comes from scientists naming a very small force inside atoms. They called it the weak force because it is much smaller than other forces, and interaction means a small 'push' or change between tiny parts of atoms, so the theory explains gentle changes like some kinds of 'radioactive decay'.
